Description
Technical field
The utility model is related to technical field of food machinery more particularly to a kind of it can solve the problems, such as food safety and sanitation
Vacuum thawing machine.
Background technology
In daily life, people are frequently utilized that freezer or refrigerator and extend the shelf life to store food, continuing its
Nutritive value, the food by frost generally require to thaw in continuing process, the solution of rising again of traditional food processing enterprise
Freeze, reaches defrosting effect of rising again by heat transfer typically by means of water, air and vacuum condensation steam medium.Its main defrosting side
Formula has following methods：1, air thawing method：Using hot-air as defrosting medium, although a kind of very original defrosting side
Method, but use still relatively generally, the reason for this is that it is at low cost, it is easy to operate, but place in air for a long time, it is easy to cause food
It is putrid and deteriorated；2, flowing water freezing process：When the food that freezes is badly in need of edible, available stream water thawing method is thawed, and specific method is to use
The food Package that hermetic bag thaws needs, is put into flowing water, if sealing is bad, the nutrition of food can be lost in, and cause to eat
Product taste deterioration；3, freezing process is heated：This method is generally used for the prepared food by boiling, and a small amount of water is added when thawing,
Then it is slowly heated with small fire, if big fire is boiled suddenly, be easy to cause that surface has thawed but the inside is still freezed；4, cold compartment of refrigerator
Freezing process：This method is the method for optimum meat defrosting, it would be desirable to which the food of defrosting is put into refrigerating chamber, can be prevented
Degree moves back ice, can also keep the cleaning of food well, but thawing time is longer, efficiency is low；5, brine freezing process：Meat is put
Enter and thaw in brine, principle is that brine can accelerate the thawing frozen, and will not grow bacterium, but can influence the quality of food materials
And taste；6, low-frequency current freezing process：Allow electric current by frozen food, electric heating, which occurs, in food product makes ice crystal melt, meeting
The quality of food is influenced, hygienic rank is relatively low；7, vacuum thawing method：Make the water in defrosting indoor water tank low using heat source
Middle benefit gas boiling vaporization is forced down, low temperature vapor carries out heat convection with frozen food, and vapor is condensed in food surface, and is released
Latent heat makes food heating thaw.Defrosting room vacuum anoxic sunset and temperature control at 10 ~ 20 DEG C, it is suppressed that part microorganism
It grows, undoubtedly it is advantageous fresh-keeping to reduce pollution for food.
The optimal above freezing process effect is vacuum thawing, it can be such that food surface is not influenced by high-temperature medium, and
And thawing time is short, and 2-3 times of efficiency is improved than air thawing method；Since oxygen concentration is extremely low, it is reduced or avoided in course of defrosting
Food Oxidation is rotten, superior product quality after defrosting；Because humidity improves, juice loss is few after food defrosting.
